Five of the pieces in the Neumeister manuscript are without a named composer. Based on stylistical grounds and on references to other sources two of these pieces can be attributed to Johan Pachelbel, two to Johann Michael Bach and one to Friedrich Wilhelm Zachow. The two prelude to "Ich ruf zu dir, Herr Jesu Christ" are thought to be composed by Johann Michael Bach. Since there is no way to know for certain, I designate it as 'anonymous' in the score, with the possibility of Bach's authorship added in parentheses. The second of these two preludes is a bit of a mess in Neumeister's transcription: voices disappaering and reappearing, seemingly at random. I tried to make it a coherent four part texture by filling in the gaps Neumeister left in his transcription.
The recording was done on the demo sample set of in the St. Valentinus and Dionysius church in Kiedrich by Sonus Paradisi for Hauptwerk (https://www.sonusparadisi.cz/en/organs/germany/kiedrich-virtual-organ-model.html).
